Multi-function power meter EMS-D3

frequency metermultimeterenergy meter

The EMS-D3 digital multimeters are made in a 3-module modular housing and are equipped with a backlit graphic LCD display that allows you to view all the electrical quantities of the system. The high accuracy of the measurements combined with its extreme compactness makes it the ideal solution for any type of application. The main measurement parameters are: • Voltage (phase, line and system voltages) • Phase current (calculated or measured neutral current) • Measurements on 4 quadrants • Power (active, reactive and apparent phase and total) • P.F. (phase and total) • Cosφ (phase and total) • Frequency • Maximum value (MAX) and average value (AVG) function • Peak values (max demand) • Total harmonic distortion (THD) of voltages and currents • Active, reactive, apparent phase and total energy meters OPERATIONAL CHARACTERISTICS • Voltage measurement range:52...690 VAC L-L | 30...400 VAC I-N • Can be used in medium and high voltage systems using TV • Nominal input current: 5A or IA with an external current transformer • Current measurements through pre-wired compact CTs (TT or TTA series sensors) (option) • Frequency measurement range: 50 / 60Hz • True RMS measurements (TRMS) • 500ms measurement update • Digital outputs (output function: alarm or pulses) • Modbus-RTU communication protocol • Programming and remote control via software • Modular housing. 3 module • Degree of protection: IP40 on front: IP20 at terminals
